Better Place may have given up on its electric vehicle battery swap technology, but Tesla is moving full-speed ahead.

Here’s what the company’s ultra-fast swap stations look like.

A few weeks ago, we speculated about the possibility of Tesla introducing battery-swapping technology into its vehicles–presumably as part of an attempt to build a battery swap station network, which the late startup Better Place failed so spectacularly to do. Turns out, the rumors were true: battery swapping technology has been buried in Tesla vehicles all along, and the company plans to launch the capability as early as this year in California and the Boston to Washington DC corridor–in the same locations as the Supercharger stations.

Earlier this evening, Tesla CEO Elon Musk demonstrated in Los Angeles that his battery swapping service stations–where customers can automatically get their used-up lithium ion batteries replaced with fully-charged ones–work faster than the fastest gas pump in town. Here’s what the demo looked like.

Battery swap services won’t be free; Musk reportedly says that the stations will charge the equivalent price of 15 gallons of gas.
